CANNING MACHINE,

Application filed May 6,

To all whom it may concern Be it known that I, CHAnLns H. AYARs, a citizen of the United States, residing at Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Canning Machines, of which the following is a specification.

My invention relates to an improvement in canning machines and its object is to provide improved mechanism for exhausting the air from filled cans. The invention consists in the parts and combination and arrangement of parts hereinafter described and claimed.

In the drawings Figure l is a side elevation showing a machine embodying my invention,

Figure 2 is a like view looking to the left of that shown in Figure 1,

Figure 3 is a top plan view Figure 4: is a plan view with t e cover removed.

Figure 5 is an enlarged horizontal section on the line 55 of Figure 1, and

Figure 6 is a vertical section on the-line 6-6 of Figure 3.

Referrin to the drawings, the numeral 1 indicates t e frame of the machine, 2 the driving shaft, 3 a gear on that shaft mesh in with a gear a on the lower end of a vertica shaft 5, 6 a gear at the upper end of the vertical shaft meshing with a gear 7 rotatably mounted on a rod 8 mounted in a casing 9 which is a stationary drum forming the peripheral and bottom walls of a heating chamber, having an inlet opening 10 and an outlet openin 11, and 12 the cover of the heating cham er. The cover is preferably made in sections 13, as shown in Figure 3, and each section is supported on casing 9 and rod 8 and provided with a loop 14 whereby it may be lifted to permit inspection of the chamber. 15 indicates a sectional perforated carrier disk carried by and rotating with gear 7. For additional support the disk has on its under side a ring or annular shoulder 16 adapted to ride on rollers 17 mounted in suitable bearingsat the bottom of the heating chamber. Number 18 indicates a gear on the driving shaft meshing with a ear 19 upon a second vertical shaft 20- whic carries at its upper end a disk 21,

hereinafter called the feed disk. The feed disk is so positioned that it projects into the inlet opening of the heating chamber and 1922. Serial R 0. 558,887.

overlaps a part of the perforated disk or carrier 15, as clearly shown in Figure Number 22 indicates a gear carried by a horizontal shaft 23 and meshing with and adapted to be driven by gear 4: on vertical shaft 5. At its other end shaft 23 carries a gear 24 which meshes with and is adapted to drive a gear 25 fixed to avertical shaft 26 which carries at its upper end a disk 27 hereinafter called the discharge disk. This disk is. so positioned that it projects into the outlet opening of the heating chamber and underlaps a part of the perforated carrier disk 15.

28 indicates a guide, carried by rod 8 and the drum, having a rail 29 adapted to guide cans from. the feed disk through the inlet of the heating chamber onto the perforated carrier and to prevent any crowding of the cans in a direction opposite to that in which the perforated carrier is rotated, and a rail 30 adapted to guide cans from the perforated carrier through the outlet of the heating chamber and onto the discharge disk.

Another guide rail 31 extending from the drum over the discharge disk prevents crowding of cans in a direction opposite to that in which the discharge disk rotates.

Steam is introduced into the heating chamber beneath the perforated carrier by a pipe 32 coiled within the drum, the part of t e pipe within the drum being perforated as indicated by 33.

The gears are so proportioned that both the feed disk and the discharge disk are rotated at a higher speed than the perforated carrier.

In operation, the heating chamber having been thoroughly heated, filled cans are placed upon the feed disk in such number that, owing to the comparatively rapid r0- tation of the feed disk, there will be a tendency to crowd cans onto the perforated carrier so that its full area will be occupied by cans. When a can reaches that part of guide arm 30 which leads to the discharge opening, there will be a series of filled cans behind it, each of substantial weight and each an engagement with one or more cans in the rear, and all being impelled forwardly by the rotating carrier, and it is obvious that the inertia of the series of cans in its rear will be sufiicient to deflect the foremost can along the guide arm and onto the discharge disk from which they may be removed for capping. As the cans are slowly carried through the heating chamber their contents are heated to such an extent that the air is completely exhausted.-

The construction above described provides a compact and substantial machine of great capacity in proportion to the space occuied. P While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a canning machine, the combination of a heating chamber having inlet and outlet openings; a rotary carrier disk adapted to move cans through the heating chamber; a feed disk overlapping the carrier disk, a discharge disk underlapping the carrier disk and means for rotating the disks.

2. In a canning machine, the combination of a casing having inlet and outlet openings; a rotary carrier disk mounted in the casing; a feed disk overlappin the carrier disk; a discharge disk underi apping the carrier disk; guide arms extending in and out of the casing for guiding cans onto and off the carrier disk and means for rotating the disks.

3. In a canning machine, the combination of a casing having inlet and outlet openings;

a rotary carrier disk mounted in the casing; a feed disk overlapping the carrier disk; a discharge disk underlapping the carrier disk; the feed and discharge disks being mounted adjacent each other; guide arms extending in and out of the casing for guiding cans onto and off the carrier disk and means for rotating the disks.

4:. In a canning machine, the combination of a heating chamber having inlet and outlet openings; a rotary carrier disk adapted to move cans through'the heating chamber; feed and discharge disks, having their peripheries projecting through the openings above and below the carrier disk respectively, for moving cans onto and from the carrier, and means for operating the feed and discharge disks at a higher speed than the speed of the carrier disk.

5. In a canning machine, the combination of a heating chamber; a rotary carrier adapted to move cans through the chamber; a feed disk; a discharge disk; a driving shaft; a vertical shaft driven by the driving shaft and carrying a gear adapted to actuate the carrier: 21 vertical shaft driven by the driving shaft and carrying the feed disk: a horizontal shaft driven by the driving shaft a vertical shaft geared to said horizontal shaft and carrying the discharge disk.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES H. AYARS.
